An international team of scientists has identified the countries most likely to preserve vital systems during a global catastrophe. The researchers considered the consequences of a nuclear war, a massive volcanic eruption, an asteroid impact, a pandemic, a global cyberattack, and a prolonged power outage.

The findings are presented in the scientific journal Global Challenges. The authors analyzed 152 scientific papers and reached a clear conclusion: there is no completely safe place on Earth. However, one country proved to be more resilient than others across the broadest range of scenarios.

What global catastrophes did the researchers consider?

The study’s authors focused not on local natural disasters but on events capable of causing mass casualties and disrupting the functioning of critical systems worldwide. By “global catastrophe,” they mean a crisis that could result in the deaths of at least 10% of the world’s population within a few months or years.

The researchers grouped all the analyzed threats into three main categories:

1. A sharp reduction in sunlight. This could be caused by a nuclear war, a supervolcano eruption, or the impact of a large asteroid. Particles of ash, dust, and soot enter the atmosphere, lowering temperatures and reducing crop yields.

2. Global loss of critical infrastructure. This refers to prolonged power outages caused by a large-scale cyberattack, a geomagnetic storm, or an electromagnetic pulse. Without electricity, transportation, communications, industry, water supply systems, and food production quickly grind to a halt.

3. Catastrophic biological threats. This group includes dangerous pandemics, accidental leaks of pathogens from laboratories, and the deliberate use of biological weapons. The main risks include mass mortality, an overwhelmed healthcare system, staff shortages, and disrupted supply chains.

The researchers assessed not only a country’s ability to withstand the initial impact. They also considered whether the country would be able to provide its population with food, energy, and medical care, restore critical systems, and adapt to a prolonged crisis.

What criteria were used to assess countries’ resilience?

The study is not a traditional ranking with scores and fixed positions. In the first stage, researchers identified approximately 3,200 publications related to global risks. After several rounds of selection and the inclusion of additional materials from subject-matter experts, 152 studies were included in the final review.

Countries were compared based on how frequently their strengths and weaknesses were mentioned in the scientific literature. Four factors emerged as the most important:

1. Geographic isolation. Large islands and remote territories can more easily restrict cross-border access. They are also less dependent on crises in neighboring countries.

2. Food self-sufficiency. A country must produce enough food and have a diverse agricultural sector. Reserves of seeds, fuel, and fertilizers are also important.

3. Quality of governance. Political stability, low corruption, public trust, and effective emergency response services help allocate resources more quickly and coordinate actions.

4. Decentralization of systems. Energy, food production, and governance should not depend on a single central hub. In this way, damage to a single facility does not lead to a complete collapse.

Additional advantages include a developed industrial sector, access to domestic energy resources, a strong healthcare system, and the ability to repurpose production. At the same time, some advantages can turn into vulnerabilities. For example, geographic isolation protects against pandemics but makes it difficult to receive international aid.

Earlier, we talked about the European countries where it is easiest to get a work visa and start a career abroad.

Why was Australia recognized as the most resilient country?

Australia was the only country that scientific sources directly identified as resilient across all three categories of global risks. It has the best starting conditions under scenarios involving a sharp cold snap, a large-scale infrastructure collapse, and a dangerous pandemic.

Australia’s main advantage lies in the combination of its remote location and significant domestic resources. The country can quickly restrict border crossings, yet it has sufficient land area, a developed industrial base, and a robust mining sector. Australian agriculture produces large volumes of food. This increases the chances of feeding the population even if international supply chains are disrupted.

The relatively warm climate could also be an advantage in the event of a nuclear or volcanic winter. The ocean moderates temperature fluctuations, and its location in the Southern Hemisphere reduces the likely severity of the consequences of a catastrophe originating in the northern hemisphere.

At the same time, Australia is not entirely self-sufficient. It depends on international trade for medicines, fuel, fertilizers, and certain industrial components. Therefore, even a country with the best indicators will need to maintain trade ties and cooperation with other nations.

Which other countries have a high chance of surviving?

After Australia, the study most frequently cited New Zealand, Japan, Switzerland, and Argentina. Each of these countries has significant advantages but remains vulnerable to certain types of global threats.

New Zealand

New Zealand, along with Australia and Japan, demonstrated resilience across all three categories of global risks. Its strengths include its remote island location, political stability, low levels of corruption, and significant food production.

The country also produces nitrogen fertilizers, and its soil phosphorus reserves could last for years or even decades. However, New Zealand has a small industrial base and is heavily dependent on foreign trade. Active volcanoes, geomagnetic storms, and tsunamis remain additional threats.

Japan

Japan has one of the world’s largest industrial bases, a well-developed healthcare system, and significant resources for responding to emergencies. The country also possesses space weather forecasting technologies, which help detect dangerous geomagnetic storms in advance.

At the same time, Japan relies on imports of food, fuel, and raw materials. High population density, an aging society, seismic activity, and proximity to active volcanoes also reduce its overall resilience.

Switzerland

Switzerland is characterized by stable democratic institutions, low inequality, and a reliable energy system. The country derives a significant portion of its electricity from hydroelectric power plants. This reduces its dependence on imported fuel. Some critical infrastructure also has additional protection.

The lack of a coastline reduces the risk of tsunamis, and the mountainous terrain can facilitate territorial isolation. However, its small size and location in the heart of Europe make the country dependent on trade and vulnerable to large-scale infrastructure collapse in neighboring countries.

Argentina

Argentina’s strengths stem primarily from its location in the Southern Hemisphere and its large agricultural sector. The country has a long growing season, extensive agricultural land, and produces large volumes of various crops.

Argentina is better equipped to withstand a sharp global cooling than many countries in the Northern Hemisphere. However, high levels of inequality and periods of political and economic instability complicate the effective management of resources during a protracted crisis.

Why Is There No Completely Safe Place on Earth?

No country is capable of withstanding all global threats equally well. An advantage in one scenario often becomes a problem in another. An island location helps control borders during a pandemic but makes it difficult to obtain resources and international aid after an infrastructure collapse.

A similar contradiction arises with industry. A large manufacturing base makes it possible to repair equipment, produce spare parts, and repurpose enterprises. At the same time, modern industry depends on electricity, digital systems, and complex international supply chains. Their disruption can quickly halt production.

The authors also caution that their findings should not be viewed as a definitive ranking. Australia and New Zealand have been studied more extensively than many other countries, which is why they appear more frequently in academic publications. Potentially resilient countries, such as Uruguay, may have received less attention simply due to a lack of specific studies.

The researchers’ main conclusion is not about finding the “last safe place.” Even the most self-sufficient countries will need international trade, technology exchange, and a coordinated response. Therefore, preventing global catastrophes remains a more effective strategy than preparing for their consequences.
